Int. Cl. A451? 3/14 U.S. Cl. 224-25 4 Claims ABSTRACT OF THE DISCLOSURE A device of the type for carrying an object on a persons back, comprising a generally fiat back portion with an upper lug for receiving the upper end of a pair of shoulder straps and two lower laterally extending lugs, each having a holding element for receiving the lower end of the straps. Each holding element is a stiff resilient member having a loop for attachment to its respective log and a ring for receiving its respective shoulder strap.

The invention relates to a carrying device comprising a back portion having a fastening member from which there extend a pair of shoulder straps and having a pair of holders for the shoulder straps and being attached to the lower part of the back portion, said holders extending forwardly from the back portion and being turnable in the horizontal plane.

The invention relates to a carrying device of this type which is particularly suited for carrying a breathing appar-atus on the back but it is also usable for a rucksack or other object.

Particularly with regard to breathing apparatus it is of great importance for the carrying device, since it supports some relatively heavy equipment, not to obstruct the movements of the wearer and to exert no pressure on the thorax, the arms or the neck.

The invention is characterized in that the upper attachments of the shoulder straps independently of each other are slidable laterally on the attaching member and the lower attachments of the shoulder straps being located at the forward end of the holders.

The drawing shows an embodiment,

FIG. 1 being an overall view of the carrying device, and

FIG. 2 a view taken on the line II of FIG. 1 and showing a holder.

FIGURE 3 is a view of a holder taken in the direction of the arrow A of FIGURE 2.

The back portion of the carrying device is designated 1 and may be of rubber or other flexible material. It is provided with three T-shaped fastening lugs, the uppermost lug 2 of which supports an elongated ring 3, on which the upper ends of a pair of shoulder straps 4 and 5 are slidable. The ring is attached to the back portion 1 by means of the stem of the fastening lug 2, which is passed through a loop 6 formed on the ring.

The lower parts 7 and 8 of the shoulder straps 4 and 5 are fastened in rings 9 and 10, respectively, provided on a pair of holders 11 and 12, respectively. The holders 11 and 12 also form loops for T-shaped fastening lugs 13, 14 provided on the lower parts of the back portion 1.

The arrangement shown having slidable upper attachments for the shoulder straps 4 and 5 and forwardly extending lower attachments formed by the rings 9 and 10 when the carrying device is in position contributes to removing pressure from the neck and the thorax of the wearer on one hand and to providing freedom of movement for the arms on the other.

The holders are of stiff resilient wire, such as steel wire, which forms a loop 15 for the T-l ug as well as the ring 9 referred to above, in which the lower end of the shoulder strap is fastened. One end of the wire forms a hook 16, into which the other end snaps in a resilient manner as shown in FIG. 2. This makes it easy to buckle on or off the holder and the vertical section of the wire snapping into the hook 16 is suitable for attaching a breathing apparatus thereto, the section being removed from the hook and the apparatus being threaded on to it, whereupon the section snaps back into locking position and the hook retains the mounted apparatus.

We claim:

1. A carrying device having a generally flat back plate having an upper T-shaped lug at its upper end, and a ring member attached to said upper lug, the upper ends of a pair of shoulder straps attached to said ring member, and a pair of lower T-shaped lugs extending laterally of said plate, a holder element attached to each said lower T-shaped lug for receiving the lower end of its respective shoulder strap, both of said holders being turnable in the same direction away from the plane of the generally flat back plate.

2. A carrying device as claimed in claim 1 wherein the holder elements are of stiff resilient wire material which forms a loop attachment to its respective lower lug and a ring for holding the lower end of its respective shoulder strap, and a hook formed at ohe end of the wire into which hook the other end of the wire snaps in a resilient manner.

3. A carrying device as claimed in claim 1 wherein the ring member comprises an elongated ring on which the upper ends of the shoulder straps are independently laterally slidable.

4. A carrying device as claimed in claim 3 wherein the holder elements are of stiff resilient wire material which forms a loop attachment to its respective lower lug and a ring for holding the lower end of its respective shoulder strap, and a hook formed at one end of the wire into which hook the other end of the wire snaps in a resilient manner.
